"I've already shown you testimony from a steel inspector who told of the
softening and twisting of the steel."

The fact that an inspector found softening and twisting of the steel only means
that -something- softened and twisted it (explosives could certainly manage
it), not that there was any evidence that the jet fuel or office fires did it.

"And the lack of concrete in the buildings core and outer
columns made the towers were more vulnerable to fire."
